Abstract
My group has led the collaborative development of a set of over 950
SNP markers for Vicia faba; of these approximately 650 have been mapped so far.
Our current consensus linkage map of faba bean consists of just 6 linkage groups
(=six physical chromosomes), each covered with a reasonable density of SNP
markers. The Vicia faba genetic map shows a high level of synteny and relatively few
chromosomal rearrangements with respect to the model sequenced legume,
Medicago truncatula. All the SNP markers developed are available as easy-to-use
KASP marker assays, and subsets of the full SNP panel polymorphic in different
segregating populations have been used to locate and obtain linked markers for
traits (so far) such as vicine-convicine and tannin content of seeds, hilum colour, and
height. In one study, we have been able to exploit local conservation of synteny to
identify and validate a candidate gene underlying the zero tannin trait. My group
has recently initiated a large EMS mutagenesis programme based the highly inbred
Hedin/2. It is our intention to screen the resulting mutant population for resistance
to herbicides to which Orobanche is sensitive
